dave, i believe the origin of the term dumbcane was
not that children or anyone else would unwittingly
chew on this plant, but that it was used as a
punishment for escaped slaves in the caribbean (to
have the cut stems rubbed inside their mouths and thus
they would not be able to speak for several days).
